What 2004 GMC Sierra 2500 owners say
Most recent owner complaints, unedited.
Emergency brakes don't engage
During cold mornings (wisconsin) I start my truck and I have no power steering and soft brakes. It is my understanding that the power steering runs the brake boost. Also, it is my understanding that there is a service bulletin that says that the power steering fluid should be replaced with low/cold temp fluid. My concern is what happens if I lose power steering and brakes while I am driving.
While driving over 50mph on the highway I get a violent shaking in the engine and the steering wheel shakes bake and forth. The engine sound very loud while its doing this. It only occurs when I am at highway speeds.
Tl* the contact owns a 2004 gmc sierra 2500. While driving approximately 45 MPH, the contact noticed a lot of white smoke emerging from the tail pipe. The vehicle was previously repaired under warranty by gwatney buick gmc (5700 landers rd, north little rock, ar 72117) for the same failure as listed in an unknown technical service bulletin regarding the fuel injectors. The vehicle was not diagnosed or repaired for the recent failure. The manufacturer was notified of the failure. The approximate failure mileage was 90,000.
Exhaust manifold bolts broken
Pulling out of a parking lot, lost brakes. Steel brake lines by fuel tank, let go causing truck to loose brakes
The instrument panel cluster gauges don't always work. We were on freeway when we noticed speedometer had failed as well as fuel gauge , temp gauge all gauges inoperative. This is third time cluster panel is being replaced; first two under warranty third time we had to pay $204.
I was traveling south on I-75 highway about 70 MPH, in motion, in northern michigan and had to stop fast when an accident occurred in front of me. I slammed/mashed my foot on the brake pedal only to feel it fall to the floor, the metal hydraulic line failed and I now have no brakes at all!! I began to press on the parking brake and down shift the transmission to assist in the slowing of the vehicle. I also steered around the stopped cars into the side and ditch of the road. I luckily had the right reactions but not all people do or cannot act as fast. This is a dangerous issue with this gmc sierra 2004. Please have it recalled. I had to have the repair shop replace all the metal brake lines as they were corroded. I have never had a vehicle fail its brake lines like this. My vehicle only has 48,000 miles on it and is garage kept super clean.
My vehicle had brake lines replace two times with less than 65,000 miles because breaks stop working. Fuel line replaced under 55,000 miles because it made check engine light come on speedometer erratic,oil pressure gauge high and low,fuel gauge erratic under 65,000 miles. Loud noise from engine service technician reported the exhaust manifold bolts has broken to call a white smoke from the motor. Everything happened with consider to be low mileage in talking to gm they don't care because enough report has not been made.
